Application April 16,

8 Claims.

My invention relates to irrigating devices and particularly to sprinklers of the rotating type, the principal objects of the invention being to provide a simple and effective sprinkler means which will distribute the greatest amount of water over the greatest area and thoroughly irrigate the area, using a part of the force of the water to rotate the sprinkler in a steady manner and controlling the force of the water to regulate the rotative movement of the sprinklers.

Other objects will appear from the subjoined specification, in connection with the accompanying drawings, which illustrate a preferred form of embodiment of the invention, and in which Fig. l is an elevational view.

Fig. 2 is a sectional elevation.

Fig. 3 is a plan view of one of the chambers with the cap removed and showing the means for producing the rotation of the sprinkler, the view being taken on lines 3-3 of Fig. 2.

Fig. 4 is a vertical section on lines 4-4 Fig. 2.

Fig. 5 is a plan detail of the means for producing rotation of the sprinkler.

Fig. 6 is an elevation of the means shown in Fig. 5 and Fig. 7 is a plan view of the axle or spindle about which the sprinkler body rotates.

The invention comprises two chambers I and 2, each provided with a cap I and 2, the chambers being in communication with each other through a pipe 3 which conjoins them near the top and through which the Water is dispensed from the chamber I to the'chamber 2 in regulable quantity for purposes to appear hereinafter, through a valve 4 that is threadedly engaged in said pipe 3 and that produces a tangential discharge of the water within said chamher 2.

Each of said chambers i and 2, is respectively provided with a nozzle 5 and 6, the latter being adjustable to alter desirably the angle of discharge of the water and thus control the speed of rotation of the sprinkler, as hereinafter pointed out.

The chamber 2 is mounted for rotation upon a vertical axle or spindle I, which is hollow and which is threadedly connectible with a source of water under pressure or to a coupling 8 as shown in Figs. 1 and 2 which may form a part of portable fixture for mounting the sprinkler. Through this spindle the water is conducted to the chamber I from which the major portion is dissipated through nozzle 5 while a lesser portion is passed through the valve 4 into the chamber 2 from which it is dissipated through nozzle 6 1935, Serial No. 16,590

after operating the means by which the sprinkler is rotated.

The spindle I is formed at the top with a tubular portion I for housing a spring 9 that is arranged to be held in compression against the 5 top of said spindle I by the cap I which as shown in Fig. 2 is socketed to receive said spring and tubular portion I. The chamber I is formed with an annular seat Ill, and the spindle I is formed with a plurality of ports II through 10 which the water enters the chamber I and an annular shoulder I2 between which and said seat It are pressed by said spring 9 a compressible washer I3 and a non-compressible washer I4, forming in this wise a water tight .engagement 5 and preventing at all times ingress of sand and other wearing accumulations between the bearing surface Ill and I4 and the shoulder I2 and compressible washer I3. The spindle I as shown, and explained forms the bearing around which the chambers I and 2 are rotatable and the means for rotating the chambers I and 2 are contained in the chamber 2, and are actuated by a portion of the water delivered to said chamber I, such portion as explained passing in controllable measure through the valve 4 in the pipe 3 which interconnects the two chambers I and 2.

The bottom of the chamber 2 is provided at one side thereof with a socket I5 which journals the pivot I6 of a lever, hammer or striker H, a collar I8 being provided to separate and elevate the hammer or lever H from the floor of the chamber 2 and provide thereby substantially a non-frictional operation of said hammer I'I between one wall of the chamber 2, as shown in Fig. 3, and a stud I9 eccentrically located with respect to the bearing I upstanding from the floor of said chamber, as presently explained. Said lever or hammer I1 is provided with a vertical pin 26 which is eccentrically disposed with respect to the pivot iii of said striker I1 and which journals a water impelled member 2| that, as it passes the pivotal center of the striker or hammer I? under the flow of the water, oscillates said hammer or lever and alternately sets and operates said hammer to deliver a continuous series of taps or blows against the stud I9 thus moving said chambers rotatively in step like continuity. The speed of rotation of the member 2| within the chamber 2 governs the speed of revolution of the chambers I and 2 and this rotative speed of the member 2! is controlled by the volume of water passing from the chamber I into the chamber 2 and this volume of water is controlled by the valve 4, which as seen in 5 Fig. 2, is a short cylindrical body preferably threading in said pipe 3 and closed at one end, the closed end being provided with a kerf 4' for a tool by which the Valve may be turned The body 4 is provided with a lateral port 4" through which the water from the chamber l passes tangentially into the chamber 2, thereby producing a whirl within the chamber 2 by which the member 2| is rotatively impelled.

With high or reasonably high water pressure, the frequency of the hammer blows against the stud I9 is great and consequently the rotation of the chambers l and 2 is rapid. In many cases rapidity of rotation is not desirable and while the speed may be controlled by the volume of water admitted to the chamber, this expedient must be coupled with a curtailment of water with resultant ineflicient wetting. The speed of rotation of the chambers may be efiiciently and flexibly regulated by adjustment of the nozzle 6 to cause the jet of water issuing from it to parallel the jet discharging from the nozzle 5 or to'discharge in any radius at an angle to the jet from thenozzle 5. A jet of water from the nozzle 6 that is parallel to the jet from the nozzle 5 acts to retard the rotation of the chambers, and the retarding influence of said jet 6 diminishes as the angle thereof with respect to the jet 6 becomes greater, a right angular discharge or nearly one assisting, rather than retarding, the hammer I! to rotate the chambers l and 2, by its reactive force which is employed only when the water pressure is low. This is a very convenient and satisfactory control without in any wise reducing the water discharged.

What I claim, is:
